Interesting. Matsuda was one of the only straight up heroes show. Though that is debatable as he does feel sympathy and under stand Kira's motivation. And it is very possible that Ryuk will drop the Death Note again. Though out of all the people trying to catch Kira Matsuda was the least intelligent. Though he may not be stupid just not as smart as L, Light, Near or Mello. So I don't think he will last long.
